ADC0834CCN/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0834CCN/NOPB is an 8-bit analog-to-digital converter manufactured by Texas Instruments, continuing the legacy of the National Semiconductor ADC0834 series. It utilizes a Successive Approximation Register (SAR) architecture to provide high-speed conversion with a sampling rate of 31.25 kSPS. The device features a multiplexer allowing for two differential, four pseudo-differential, or eight single-ended inputs. It operates on a single 4.5V to 6.3V supply and communicates via a serial interface compatible with SPI/QSPI/MICROWIRE standards. Packaged in a 14-pin PDIP, it supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity as the ADC0834 family has been discontinued by Texas Instruments. Ensure the NOPB suffix confirms lead-free compliance if required by specific manufacturing standards. Check current distributor availability as stock levels may be limited due to end-of-life status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and moderate speed are sufficient for the application. Consider the input configuration requirements; choose between differential or single-ended modes based on noise immunity needs. Verify that the serial interface timing matches the host microcontroller's capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC083x family, which includes variants with different resolutions and channel counts. The ADC0834 specifically offers 8-bit resolution with a multiplexer. It serves as a cost-effective solution for general-purpose data acquisition tasks where high precision is not critical.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same package may include other members of the ADC083x family, such as the ADC0831 or ADC0838, provided the resolution and channel count meet system requirements. Verify electrical specifications against the original design constraints.
